A deficiency state of vitamin D is typically brought about by:______________?
Show answer Hide answer
Answer: C. Rickets
Explanation
Rickets is a deficiency disease directly caused by an inadequate supply of active vitamin D in childhood. Without sufficient vitamin D, children cannot absorb enough calcium and phosphorus to mineralize growing bones. This nutritional deficiency softens the skeletal structure, leading to distinct physical deformities and stunted growth patterns. Vitamin D functions as a hormone that regulates calcium and phosphorus homeostasis in the human body. Nutritional rickets was historically prevalent in industrial cities where children experienced very little direct sunlight exposure. Fortifying common foods like milk with vitamin D drastically reduced rickets rates across developed nations.
Beri Beri is caused by a deficiency in vitamin B1, also known as thiamine, rather than vitamin D. Scurvy results specifically from a lack of vitamin C, leading to connective tissue degradation and bleeding gums. Night blindness is an eye condition triggered by an insufficient dietary intake of vitamin A for vision.
